Silicone anti-adhesion agent/Silicone surfactant SF501
General
A three components solventless system special design for PEK ect.substrate Coating.
• Siemtcoat® SF501 (Main polymer）
• Siemtcoat® 8982（Crosslinker）
• Siemtcoat® 5000 (Catalyst)
Application
The SF501 is special design for PEK ect. substrate coating. The dosage of different component should be adjusted base on different process condition and application. After mixed components even, the coating on the substrate surface to curing and achieved the target release profile.
Advantage
● Long bath life and good anchorage performance with additive add in
● Low silicon migration
● Suit for different type adhesive system

Processing
When applicate SF501 into Siemtcoat system, please following bellowing ratio and mixing process：
1- Weight the main polymer SF501-----100p
2- Weight the crosslinker
Siemtcoat® 8982-----2.7-2.9 p 3- Mix the crosslinker and make sure it was dispenser well.
4- Weight the catalyst Siemtcoat®5000 and add in during mixing Siemtcoat®5000-----1.1-1.3 p
(Attention： do not mix the crosslinker and catalyst directly as dramatic reaction would happen.)
5- Mix until the catalyst even.
The detail information could consult us for the formulation advice.
Bath life
All Siemtcoat system bath life is relative to the formulation, equipment, mixing process, temperature and environment. SF501 additive would not change the Siemtcoat original bath life (Normally about 5 hours at 40℃)
Release force
Release force performance is relative for many factors.
We measure the release force with different substrate and adhesive to define the release force performance. While the standard release force measure could use standard tape to measure.
Typical release force performance:tesa Tape 7475 (23℃) — 10 to 20 g/25mm （0.3m/min peeling speed）
Curing
Siemtcoat system curing results is relative the formulation, quality for substrate, curing temperature and oven efficiency. We acquired the following results :
|

Curing time |
|
120℃ |
Glassine |
＜14 s |
|
PEK |
＜12 s |
(Curing time define as the minimum curing time without smear, no rub-off and migration of release coating layer)
